Course

The course is 82% single-track trail and 18% dirt fire roads, with a total of about 300 yards of pavement. The trail is consistently rolling with three significant climbs. There is about 10,500 feet of elevation gain and an equal amount of loss over the 50 miles. Trail quality is generally good; there are very few rocks and almost no roots. However, much of the trail is seldom used and so you can expect a lot of leaves and sticks on the trail.

Drop Bags

Will be transported to the Warm Springs Creek aid station, which you will pass at mile 12.1 and 37.9. With that, you can change into lighter clothing for the middle of the day and slower runners can have warmer clothing and a flashlight for the last 12 miles. Please try to limit the size of your drop bag to no larger than a small shoebox. We are happy to allow for drop bags, but not particularly interested in moving all your worldly possessions.
